I'm afraid I treat my knives like I do my guns. I can always justifiy buying a new one, but never see the need to get rid of any.
I'm an old fart (50) and have been buying knives since I was a kid. Never sold any and only lost one.
One of my proud moments as a father was when I was a Scout leader and we were doing the section on knives.
I decided to take my knife collection for show and tell. I had no idea how many I had until I started gathering them up in a duffle bag.
When layed out on display they completly covered the top of an 8 ft folding table.
I talked about each one, knife safety, etc.
After class while I was putting all my knives away I heard one of the kids tell my son that "He wished he had a cool Dad like his".
